Claims (7)

The color image of the skin, 1) R, G, decomposed into components of B, after reconstitution of the B channel image consisting of the components of the R channel image and the B consisting of the components of the R, 2) separately L * a color mode of the color image, a *, b * into a color system, L *, a *, and decomposed into b * components, consisting of the a * component a * channel image the reconstituted, 3), characterized in that the B-channel image to adjust by the a * channel image and the R-channel image, how to create a skin image. 2. The skin according to claim 1, wherein the method for creating a skin image is for separating an image region of an inflammatory site, a pigment cell layered site, and a pigment cell infiltrating site from the skin image. How to create an image. The method for creating a skin image according to claim 2 , wherein the stratified region of the pigment cell is a tumor. The method for creating a skin image according to claim 3, wherein the tumor caused by the stratification of pigment cells is a mole. Wherein the B channel image can be adjusted by the a * channel image and the R-channel image, by adding the a * channel image to the B channel image was created by inverting the brightness of advance R-channel image from can image inversion characterized by adjustment by adding the R channel image, the method creates a skin image according to any one of claims 1 to 4. The method for creating a skin image according to claim 1, wherein adjusting the B channel image with the a * channel image and the R channel image manipulates a skin image according to the following steps: .
( Step 1 ) For the B channel image (1) and the a * channel image (2), the redness of the skin image is dynamically canceled by the addition of the B channel image (1) and the a * channel image (2). The range is adjusted, and a dynamic range adjustment B channel image (3) or a dynamic range adjustment a * channel image (4) is created.
(Step 2 ) Dynamic range adjustment B channel image (3) and a * channel image (2), or B channel image (1) and dynamic range adjustment a * channel image (
For 4), the dynamic range adjustment B is performed so that the background luminance becomes equal to the background luminance of the original B channel image (1) or a * channel image (2) by adding the two sets of images. The luminance level of the channel image (3) and the a * channel image (2), or the B channel image (1) and the dynamic range adjustment a * channel image (4) are corrected at the same rate, and the dynamic range adjustment B channel image (5 ) And dynamic range reduced a * channel image (6), or dynamic range reduced B channel image (7) and dynamic range adjusted a * channel image (8).
(Step 3 ) The dynamic range adjustment B channel image (5) and the dynamic range reduction a * channel image (6) are added, or the dynamic range reduction B channel image (7) and the dynamic range adjustment a * channel image ( 8) and by adding the, to create a dynamic range adjustment B + a * channel image (9).
From (Step 4) Installing elaborate skin image, and create R-channel image (10), the dynamic range adjustment B + a * channel image (9) and R-channel image (10) and the step 2, the procedure of Step 3 accordingly the dynamic range to adjust, the dynamic range adjustment B + a * channel image (9), by adding the inverted R-channel image creating (11) inverts the luminance of the pre-R-channel image (10), the dynamic range adjustment B + a * + inverted R-channel image to create, and the final skin image. Created by creating a skin image according to any one of claims 1 to 6, and B + a * + inverting said R-channel image the B channel image a * adjustments in channel image the B + a * image A method for discriminating between a pigment cell layered portion and a pigment cell infiltrating site, characterized by comparing and distinguishing.
